The main aim of this paper was to investigate the activity response of the antioxidant enzyme GSHPx and TBARS content in rumen bacterium Selenomonas ruminantium following expo-sure to HgCl2 in the presence of plant nonenzyme antioxi-dants substances (AOS). S. ruminantium was grown alone or together with alpha-toc, beta-car or with 5 mg.ml-1 of HgCl2 alone or together with tested AOS. The activity of GSHPx and TBARS contend of S. ruminantium were estimated in supernatants of disrupted bacterial cells. A significant changes in the S.ruminantium GSHPx activity and TBARS content in the presence of HgCl2 and tested AOS was observed. The potential role of plant antioxidants in elimination of the environmental stress of ruminal bacteria stimulated by heavy metals is discussed.
